Reviewer scorecard
“This is the kind of tool that makes you wonder how you worked without it.”
“For webpack-heavy projects, Rspack provides the biggest speed improvement with the least migration effort.”
“The free tier is genuinely usable. Rare for this category.”
“webpack compatibility with Rust speed. The migration path from webpack is smoother than switching to Vite or Turbopack.”
“Rust-based JS tooling replacing JavaScript tooling is the trend. Rspack, Biome, and SWC prove it works.”
